On November 2, 2026, Hai Au Medtech co-organized a scientific workshop themed “Application of Radiofrequency (RF, PRF) in the Treatment of Chronic Pain Caused by Spinal Disorders and Cancer” at Phu Tho Provincial General Hospital.
The program featured in-depth lectures and professional sharing by renowned pain management specialist Dr. Olav Rohof (MD, PhD, FIPP), alongside the participation of numerous physicians from various hospitals. This was a valuable opportunity for doctors to update advanced clinical knowledge, exchange practical experiences, and approach modern breakthroughs in chronic pain control.

Chronic pain resulting from spine pathology and cancer is a complex clinical condition that significantly impacts patients' quality of life, mobility, and psychological wellbeing. Identifying safe, effective, and tailored pain management techniques remains a paramount objective in modern medical practice.
During the workshop, Dr. Olav Rohof and participating doctors focused on the clinical applications of two advanced radiofrequency techniques:
- Continuous Radiofrequency (RF): Utilizes thermal energy generated by high-frequency currents to target neural pathways responsible for pain transmission, providing effective relief for indicated spinal and joint pathologies.
- Pulsed Radiofrequency (PRF): Employs high-frequency energy pulses to achieve neuromodulation while minimizing thermal tissue destruction, providing an expanded therapeutic choice for diverse chronic pain conditions.
